Functionality

The circuit-breaker condition monitoring function SSCBR is used to monitor different
parameters of the circuit breaker. The breaker requires maintenance when the number
of operations has reached a predefined value. The energy is calculated from the
measured input currents as a sum of I
calculated values exceed the threshold settings.
The function contains a blocking functionality. It is possible to block the function
outputs, if desired.
